It allows the page to save the users input on a form across
postbacks. It saves the server-side values for a given
control into ViewState, which is stored as a hidden value on
the page before sending the page to the clients browser.
When the page is posted back to the server the server
control is recreated with the state stored in viewstate.

Enableviewstate propery is on for page or any control then
it holding or catching or storing data in memory as well as
client side hedden value. when u post back data remains in
control or page.
if Enableviewstate property false then data remove when
post back.

Web page is a stateless entity. To preserve data between
postbacks dot net provided to containers viz. ViewState and
Session.

Viewstate enables persistence of data across post backs in
web forms of dot net (web pages). The data is stored in
hidden field/s of the page. Hence data travels across
media between server and client making loading and un-
loading slow. The advantage is every page will have its
own viewstate data. Normally web controls will have
viewstate enabled. If viewstate is turned off, other data
also can be saved in viewstate.

Objects have to be serialised before putting in viewstate.
While accessing methods and properties of an object the
object has to be properly type casted.

At times, viewstate of a page can get corrupted, requiring
the whole application to be re-started. It is not good
idea to keep large objects in viewstate.

If performance is the issue turn off viewstate, if
persistence is the issue and you have small to medium sized
data enable viewstate.

Keeping state in Sessions is also a better solution.

Hello, Using Visual Studio 2005 (VB) I am working to create a Web Site implementing the following: Within a gridView I have placed a dropdownlist control with a DataSourceID="SDSLkupList". SDSLkupList is a sqlDataSource used to store a lookup list for dropdownlist translation from ID to text. SDSLkupList contains the translation text and other fields related to the dropdown selection ID. (Thought it would be efficient to get everything at the same time.) I would like to provide the user the ability to select from the dropdownlist and, based on the selection, use labels to list related columns stored on the SDSLkupList in separate gridView columns. I have read that SqlDataSources are not meant to be used for individual controls. Since SDSLkupList contains all related information, is there a way to do a find using the dropdownlist selectedValue? (I was not able to discover one.) Otherwise, what should I use? It would need to set the labels on the gridView DataRowBound event as well as the SelectedIndexChanged events. Has anyone done this? Any help would be appreciated. Thanks in Advance. Neal
